Diagnostic Procedure

Do you have CONSULT-II?

Yes or No

• Yes: GO TO 2.
• No: GO TO 3.

With CONSULT-II 

1. Turn ignition switch to "ON" position. (Do not start engine.)
2. Select "DATA MONITOR" mode for "A/T" with CONSULT-II.

3. Read out P/N, R, D, 2nd position switches moving selector lever to each position.

   Check that the signal of the selector lever position is indicated properly.

   NOTE: "2 POSITION SW" indicates L position status.

OK or NG

• OK: GO TO 8.
• NG: GO TO 4.

Without CONSULT-II 

1. Turn ignition switch to ON position. (Do not start engine.)
2. Check voltage between TCM harness connector E143 terminals 27 (P/B), 34 (G), 35 (G/W), 36 (R/G) and ground while moving selector lever through each position.

   0: 0V 

OK or NG

• OK: GO TO 9.
• NG: GO TO 4.

Check the following item:

• Park/neutral position (PNP) switch

  Check continuity between PNP switch harness connector F29 terminals 1 and 2 and between terminals 3 and 5, 6, 7, 8 and 9 while moving manual shaft through each position.

OK or NG

• OK: GO TO 7.
• NG: GO TO 5.

Check PNP switch again with manual control cable disconnected from manual shaft of A/T assembly. Refer to Step 2 (With CONSULT-II) or Step 7 (With out CONSULT-II).

OK or NG

• OK: Adjust manual control cable. Refer to "CONTROL CABLE ADJUSTMENT ".
• NG: GO TO 6.

Remove PNP switch from A/T assembly and check continuity of PNP switch terminals. Refer to Step 3.

OK or NG

• OK: Adjust PNP switch. Refer to "PARK/NEUTRAL POSITION (PNP) SWITCH ADJUSTMENT ".
• NG: Repair or replace PNP switch.

Check the following items:

• Fuse
• Harness for short or open between ignition switch and park/neutral position (PNP) switch
• Harness for short or open between park/neutral position (PNP) switch and TCM
• Harness for short or open between park/neutral position (PNP) switch and combination meter
• Harness for short or open between combination meter and TCM
• Ignition switch

  Refer to "POWER SUPPLY ROUTING CIRCUIT ".

OK or NG

• OK (With CONSULT-II): GO TO 8.
• OK (Without CONSULT-II): GO TO 9.
• NG: Repair or replace damaged parts.

With CONSULT-II 

1. Turn ignition switch to "ON" position. (Do not start engine.)
2. Select "DATA MONITOR" mode for "A/T" with CONSULT-II.

3. Read out "OVERDRIVE SW".

   Check the signal of the overdrive control switch is indicated properly.

   (Overdrive switch "ON" displayed on CONSULT-II means overdrive "OFF".)

OK or NG

• OK: GO TO  10.
• NG: GO TO 9.

Check the following item:

• Overdrive control switch

• Check continuity between A/T device (overdrive control switch) harness connector M34 terminals 1 and 2.

OK or NG

• OK: GO TO 10.
• NG: Repair or replace damaged parts.

Check the following items:

• Harness for short or open between combination meter and A/T device (overdrive control switch)
• Harness of ground circuit for A/T device (overdrive control switch) for short or open
• Combination meter

  Refer to "COMBINATION METERS ".

OK or NG

• OK (With CONSULT-II): GO TO 11.
• OK (Without CONSULT-II): GO TO 12.
• NG: Repair or replace damaged parts.

With CONSULT-II 

1. Turn ignition switch to "ON" position. (Do not start engine.)
2. Select "DATA MONITOR" mode for A/T with CONSULT-II.
3. Read out "CLOSED THL/SW" and "W/O THRL-SW" depressing and releasing accelerator pedal.

   Check the signal of throttle position signal is indicated properly.
